N-ary puzzles go back hundreds of years, with parts that move back and forth in highly systematic yet confusing patterns, having solutions that require a number of moves exponential in the number of moving parts.
Karakuri craftsman Hiroshi Iwahara is particularly well known for bringing the concept of n-ary puzzles to Japanese puzzle boxes. 5 times 5 times 5 is one of his best, requiring a whopping 125 moves to open and utilizing moves across all 6 faces. Simply brilliant. Plus it not only looks great but feels great – it is larger than typical cube-shaped Karakuris and has a satisfying heft to it. All original packing material is included.
